What’s the difference between hei cha and pu’er?
Both are post-fermented, but hei cha is a broader category defined by regional styles (Anhua, Liu Bao, etc.) and often uses different microbial cultures and leaf grades. Pu’er is strictly from Yunnan and has its own appellation rules.
What are ‘golden flowers’?
‘Golden flowers’ (<em>Jīn Huā</em>) are colonies of the beneficial fungus <em>Eurotium cristatum</em>, which develop internally during ageing of <em>Fú Zhuān</em> bricks. They contribute a sweet, medicinal note and are a sign of careful fermentation, not spoilage.
Does hei cha improve with age?
Yes, like pu’er, hei cha mellows and deepens with time. A five‑year‑old brick will be noticeably smoother and sweeter than a fresh one, provided it’s stored correctly.
How should I break a <em>Fú Zhuān</em> brick?
Use a tea needle or a sturdy butter knife, working along the compression layers. Pry off only a small chunk at a time to keep the rest of the brick intact for ongoing ageing.
Can I brew hei cha in a gaiwan?
Absolutely. Use 5–6 g per 100 ml, rinse once, then start with short 10‑second infusions. You can also simmer the leaves in a pot for a richer, more medicinal brew after the first few steeps.
